Re: [Pydev-users] heap overflow error

[Fabio Z. <fa...@gm...>]

The code to look at is probably:

java.lang.OutOfMemoryError: Java heap space
        at java.util.Arrays.copyOf(Arrays.java:2894)
        at
java.lang.AbstractStringBuilder.expandCapacity(AbstractStringBuilder.java:117)
        at
java.lang.AbstractStringBuilder.append(AbstractStringBuilder.java:532)
        at java.lang.StringBuffer.append(StringBuffer.java:323)
        at java.io.BufferedReader.readLine(BufferedReader.java:362)
        at java.io.BufferedReader.readLine(BufferedReader.java:379)

org.python.pydev.editor.codecompletion.revisited.PythonPathHelper.markAsPyDevFileIfDetected(PythonPathHelper.java:588)
        at

        at
org.python.pydev.navigator.PythonBaseModelProvider.wrapChildren(PythonBaseModelProvider.java:790)

It seems that PyDev is opening a file which may be a huge binary file and
is checking if it has a shebang, but to do that it tries to read the first
1-2 lines, which in this case seem to be taking the whole heap.

A better approach could be reading the first/second line but with a limit
of  XX chars.

Please create a ticket in the PyDev tracker at
http://sw-brainwy.rhcloud.com/ with this information.

Cheers,

Fabio
